I have a Qt Designer form (widget), that includes N radio buttons. And i want to see different options (QGroupBox, etc) depending on selected button in the same widget. What is the right way to solve this problem?
Of course, i can place all boxes in widget and change their visibility depending on selected radio button, but that is not perfect i'm sure.
It seems like QStackedWidget is what you're looking for.
Put your radio buttons into a QButtonGroup, then connect QButtonGroup::buttonClicked(int) to QStackedWidget::setCurrentIndex(int).
